The outer heads, and the present application is a continuaend of head A is materially widened and is protion-in-part of my copending application for U.

In Fig. 3 a ring 20 of small circular cross-section is used having a relatively deep annular recess 20a in its inner periphery for receiving the annular rib A3 of the spray head; and in Fig. 4 a somewhat similar ring is shown in which the annular recess 30a is shallow to t the rib A3 of a spray head of slightly different shape. In both Figs. 3 and 4 the rings 2O and 30 do not seat in a recess A4, but project below the spray face A2 so that the heads may be used to forcibly clean the drain pipe o1 the sink in the same manner as above described with respect to the head in Fig. 2.

I claim:-

1. In combination with a spray head having an open face and having an outwardly extending annular rib adjacent the open face, a resilient bumper ring of substantially circular cross-section stretched around the head making a tight Contact with the rib; the ring having an annular recess in its inner periphery for engagement with the rib for locking the same thereon.

2. In combination With a spray head having a spraying face and having an annular exterior rib adjacent the spraying face, and having an annular recessed portion adjacent the rib; a resilient bumper ring of substantially circular crosssection stretched around the recessed portion, said ring having an annular recess in its face receiving the rib for locking the ring on the head.

3. In combination with a spray head having a spraying face and having an annular exterior rib adjacent the spraying face, and having an annular recessed portion adjacent the rib; a resilient bumper ring of substantially circular cross-section stretched around the recessed portion, said ring having an annular recess in its face receiving the rib; and the ring protruding beyond the spraying face of the head for effecting a tight seal beyond the spraying face, when contacting With a surface.
